Subsection 13 Software management control Flashcards
A lack of adequate control of aircraft field loadable software ( FLS ) and database field loadable data ( DFLD ) has been addressed by the UK CAA and to make Licensed engineers aware of the issues of software restrictions and their responsibilities in this regard in their publication?
Civil aircraft airworthiness information and procedures
An aircraft system allocated a critcally category of hazardous has a software level of
B
An aircraft system allocated a software level āCā that should it fail due to a software error may cause?
Injuries to some occupants
An aircraft system that, should it fail due to a software error, would cause a significant reduction in safety margins may also cause?
Injuries to some occupants
An aircraft system that, should it fail due to a software error would cause a slight increase in crew workload has a software level of?
D
An aircraft system that, should it fail due to a software error would cause a no injuries to occipants has a critcality catagory of?
Minor effect
An aircraft with a software level D should it fail due to a software error ma cause?
The aircraft safety margin to be slightly decreased
